RIM is poised to unveil the first two smartphones running BlackBerry 10 at its events, along with availability, specs and pricing information. Just a few short years ago, BlackBerry was the dominant smartphone operating system in the U.S., but has since been fallen off sharply as consumers shifted en masse to smartphones running Google's Android and Apple's iPhone, which runs iOS.
